Reliability Incremental Routing for Power Line Communication Based on Power Internet of Things

In the field of electric power, power communication network is an important part of smart grid, and the number of communication nodes exceeds one billion. With the rise of new services such as power Internet of things automation, photovoltaic cloud network, energy storage cloud, Internet of vehicles, source network and load interaction system, higher requirements are put forward for the reliability and real-time performance of communication. This paper analyzes the communication requirements of the emerging services of the power Internet of things, establishes the evaluation method combining direct reliability and indirect reliability, and puts forward the reliability incremental routing method of power line communication based on delay constraint. Through simulation, it can be concluded that the reliability incremental routing algorithm proposed in this paper has certain advantages in reliability and time delay. In the power Internet of things, it can meet the demand of reliable communication business of power Internet of things, and improve the level of power grid intelligence.
